Transport of swift heavy ion induced electrons in solids

We investigated the transport of heavy ion induced electrons in solids by both numerical simulations and measurement: Electron yields and double differential spectra of electrons have been studied as a function of target thickness d. We measured electron yields from the beam entrance and exit surfaces of thin carbon foils bombarded with swift highly charged heavy ions at 13.6 MeV/u (Ar; foil thickness d approximate to 4 mu g/cm(2)-360 mu g/cm(2)) and 74 MeV/u (Ni, d approximate to 3 mu g/cm(2)-50 mg/cm(2)) and compared the results to numerical simulations. Also, double differential (in velocity and angle) spectra of electrons emitted into the forward direction from C foils induced by Ar17+ at 13.6 MeV/u reveal the dependence of the shape of the ''binary encounter'' electron peak on thickness d.
